I've also used it during event photography to transfer a shot to my iPhone for quick editing in iPhoto so that I can upload it to the event's Facebook page.
Thanks for the sample usage scenarios, but it is undisputed that wifi is useful for quick uploads - I'm wondering specifically about the remote control/shoot part that has received a lot of marketing hype, is it really being used regularly after the first "well, I can do this and that" experiments?
I'm not sure what the marketing hype is, but the ways I listed before are the ways I personally use it. Like I said, I don't use it often, in the same way I don't use a remote trigger often. Occasionally, though, I'll run into a situation where it will help me out so I use it (maybe once a month or so). I don't shoot wildlife so I can't specifically speak for that. It's a good feature to have and very helpful for those random moments when you need it, but I wouldn't expect it to completely change somebody's shooting style or be used every day.
